Severed arm found near Quality Inn may belong to missing "Thundercats" comic book writer Stephen Perry

Zephyrhills, Florida - Stephen Perry is a comic book writer, known for his work on a series called "Thundercats."

But it's his story that may come to a tragic end.

Up until Saturday, he'd only been part of a missing person's investigation.

Police found his Zephyrhills home ransacked earlier this week, with no sign of the 56-year-old, who hasn't been seen for two weeks.

Police now say the case is being called a possible homicide.

Perry's two roommates, Roxanne and James Davis, had also been missing until their Friday arrests on unrelated drug charges.

They appeared in court on Saturday.

Some neighbors tell 10 Connects the two only recently moved in with Perry, who has cancer.

They say the Davis's may have only wanted to get Perry's pain medicine.

"That could be a possibility. Definitely a possibility why these two roommates would have done this, if they did do it," said neighbor Rachel Benson.

Among the clues invesgators are working with is Perry's van. It was found at the Quality Inn off of I-275 in Hillsborough County. Nearby, a severed arm was discovered, but police won't say who's.

10 Connects found a letter, claiming to be written by Perry, on the website thundercatslair.org.

It paints a desperate picture of Perry's apparent troubles recently, saying, "I've got cancer, my wife left, I lost my job, went homeless, and now I'm very sick, trying to survive and take care of my five year old son with nothing."

Police say all the evidence in the case is being examined by the Florida Department of Law Enforcement crime lab in Tampa.

Lab test results are expected early next week, which could provide more answers.
